We report the case of a 49-year-old woman with severe elbow ankylosis 10 weeks after a trochlea fracture treated with open reduction and internal fixation. Imaging confirmed failure of open reduction and internal fixation with a displaced and severely damaged trochlea. We treated the nascent malunited trochlea and associated elbow ankylosis with a distal humeral hemiarthroplasty and circumferential elbow arthrolysis. The patient regained functional range of motion of the elbow and had minimal pain. Distal humeral hemiarthroplasty, which has been indicated for acute fractures involving the capitellum or the entire distal humerus, may also be indicated for certain isolated complex fractures of the trochlea.
我们报告了一例49岁女性病例，该患者在接受切开复位内固定治疗滑车骨折10周后出现严重的肘关节强直。影像学检查证实切开复位内固定失败，滑车移位且严重受损。我们采用肱骨远端半关节置换术和肘关节周围关节松解术治疗新生的畸形愈合滑车及相关的肘关节强直。患者恢复了肘关节的功能活动范围，疼痛轻微。肱骨远端半关节置换术已被用于治疗涉及肱骨小头或整个肱骨远端的急性骨折，对于某些孤立的复杂滑车骨折也可能适用。
